vladimir duthiers is live in abuja with the latest on this. vlad, what kind of difference can these drones and these extra troops make? >> reporter: hey, john, good morning. well, this is going to make some difference, because up until this point, the nigerian military, six weeks on after these girls were abducted in the middle of the night from their dormitories, has not been able to locate them. the president of nigeria, goodluck jonathan, saying he has no idea where they are, but he has 20,000 nigerian troops in northeastern nigeria actively searching for these girls, still coming up empty-handed. so, whatever the united states, france and china, the other countries surrounding nigeria, chad, niger, cameroon, benin, putting each battalion of troops on the ground to help locate these girls, it's going to hopefully do something to bring a resolution to this, but six weeks on, we still have no idea where these girls are. and for the parents waiting for some kind of hope, some semblance that these children will be back to them, they're going to have to be waiting for some time to come, john.
